SAN FRANCISCO –– A California statue court has denied Monsanto’s efforts to obtain summary judgment in a Roundup exposure lawsuit, finding that the plaintiff had proffered expert testimony sufficient to satisfy both general and specific causation.

In the May 16 order, the California Superior Court for San Francisco County weighed in on a number of motions pending on both sides, mostly rejecting efforts by both parties to exclude testimony from experts on the opposing side.

Plaintiff Dewayne Johnson filed the underlying lawsuit, contending that he developed non-Hodgkin’s lymphoma as a result of exposure to Monsanto’s Roundup herbicide.
